Title: Apparatus for dissolving agranulate, primarily a predetermined quantity of ferrous sulfate granulate with water.
Inventor: HOVAD KARL ERIK
IPC: B01F1/00
Filed: 1990-07-10
Abstract: A mixing tank (1) for the continuous mixing of ferrous sulphate granulate with water. The mixing tank (1) comprises two parallel plastic pipes (2', 2'') positioned helically on the bottom (3) of the tank (1), the upper sides of said pipes having the same water discharge outlet area per area unit of the bottom (3) of the tank (1). As a result, water is always distributed evenly for percolation through the ferrous sulphate solution, thus always producing a ferrous sulphate solution of a "saturated" concentration. The manufacture of the mixing tank (1) is therefore considerably quicker and cheaper than the manufacture of known types of mixing tanks, said mixing tank also being more economical in operation and smaller in dimension than known types of mixing tanks having the same output.

Title: Production of biologically active insulin-like growth factor i from high expression host cell systems.
Inventor: MILLER JAMES A
IPC: C07K14/65
Filed: 1990-08-21
Abstract: A novel method for refolding reduced IGF-I is provided in accordance with the present invention. The method is carried out by providing additional positive charge at the amino terminal end of the IGF-I molecule by the presence of a short leader sequence. The additional positive charge on the met-end of the IGF-I molecule has been found to enable recombinant IGF-I to refold simply by stirring solubilized inclusion body protein for between 2-16 hours, or overnight. The present invention also provides a novel fusion protein intermediate of IGF-I attached to the positively charged leader sequence.
